42RLE Valve Body 2003, remanufactured and ready to install. Fits the 42RLE. Ships fast from the USA.
A 2003 42RLE that shifts hard, hangs before engaging, or drops into limp mode with a stored code is usually a valve body problem rather than worn clutches. 2003 was the first model year Chrysler put the 42RLE into both the Jeep Wrangler TJ and the brand-new Jeep Liberty KJ, and this OEM-spec valve body replaces the worn unit on those early production units with a bench-tested part instead of a rebuild.
Chrysler built the 42RLE on the older rear-wheel-drive-based 30RH/32RH architecture but added electronic shift control borrowed from the 41TE program. The valve body carries that control: line pressure from the pump passes through its bores and spool valves to apply the low/reverse, 2-4, overdrive and underdrive clutches on command, and the governor pressure and shift solenoids mounted on the body execute the signals the transmission control module sends. On an early 2003 unit, wear in those bores or a sticking governor pressure solenoid is the most common reason shift quality falls apart even when the clutches underneath are still good.
Pull codes and check the adaptive Clutch Volume Index values the transmission control module stores for each clutch before you replace anything. A high CVI on a specific clutch points at that clutch pack; solenoid or governor pressure codes with normal CVIs point at the valve body. Our Chrysler Ultradrive problems guide and slipping-under-load guide cover that same CVI-based diagnosis Chrysler used across the 41TE and 42RLE control strategy.
2003 was the launch year for the 42RLE in both the Jeep Wrangler TJ and the first-generation Jeep Liberty KJ, and early-production valve bodies can differ in casting and connector from the versions that followed later in the model run. Match the casting number and solenoid connector on your old unit, or send your year, make, model and VIN so we can verify fitment before you order. See every 41TE/42RLE-family part we stock on the 41TE parts page.
Pull the pan and service the fluid and filter at the same time so debris from the old valve body doesn't travel into the new one. If the symptoms point at low or erratic line pressure rather than a single bad shift, check the governor pressure solenoid and the 42RLE pump while you're in there, since a worn pump will make a good valve body look bad. Torque the bolts in sequence to spec, refill with ATF+4, and run the transmission through a full set of shift cycles so the adaptive controller relearns against the new part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
2003 was the first model year for the 42RLE in both the Jeep Wrangler TJ and the first-generation Jeep Liberty KJ.
Early-production units can differ in casting number and solenoid connector from later model years, so match your old unit's casting and connector or send your VIN before ordering.
ATF+4 only.
A governor pressure solenoid fault usually shows up as erratic or inconsistent shift points and a stored governor pressure code, while broader valve body wear causes harsh, delayed, or slipping shifts across multiple gears. Checking stored codes and CVI values narrows it down before you order parts.
Service the fluid and filter at the same time, and check the governor pressure solenoid and pump while the pan is down since a worn pump will make a good valve body look bad.
Pull the stored Clutch Volume Index values. A high CVI on one clutch points at that clutch pack; solenoid or governor pressure codes with normal CVIs point at the valve body.
